Resilient video coding for wireless and peer-to-peer networks

The work that resulted in this thesis was carried out at Delft University of Technology in three different projects.In each of these project video coding was part of the research, but every time the emphasis was put on a different viewpoint towards video coding was taken.The first project, Ubiquitous Communications (UBICOM), was totally funded by the Delft University of Technology.The UBICOM scenario was a low-power wearable augmented reality system where a virtual world could be projected onto the real world, using semi transparent virtual reality helmet.In the Context Aware User and Terminal (CACTUS) project a modern user, equipped with wearable devices was central.Devices, worn by the user or integrated in rooms, buildings, cars, etc, will be able to communicate with each other in an ad hoc manner.To support his tasks, his personal device communicates and negotiates on his behalf user with other devices such as screens, input devices and for instance vending machines.CACTUS, as sub project of the FREEBAND project, was funded by the Ministry of Economic Affairs in The Netherlands.In the I-SHARE project, we focused on sharing resources and data among devices, people and groups of people.In this scenario, Internet wireless networks and peer-to-peer (P2P) networks play an important role to interconnect devices and to facilitate sharing.I-SHARE was also funded by the Ministry of Economic Affairs, as a sub project of the FREEBAND project.This thesis concentrates on the aspect of video compression in these projects.Each project had a different viewpoint on video compression.Not only the scenario in which compression was used differed, but also the chosen solutions to implement video compression.Although we concentrate on video compression, we approach the task of video compression from the environment in which it has to operate, namely a networked device, from which different constraints are imposed on the video coder.
